Biography
Chagatai was born on 22 December 1183 to the Tengri Borjigin clan of Mongols, and he was the son of Genghis Khan and Borte. On his father's death in 1227, Chagatai Khan inherited the Central Asian regions of the Mongol Empire, which became the Chagatai Khanate, named for him. His capital was at Almaligh in present-day Almaliq, Xinjiang, China, and during his reign he was tolerant of Islam, as mosques and colleges were built during his reign. In 1232 Chagatai put down sedition at Bukhara that could have boiled over to become a calamity, and Chagatai maintained peace in his empire during his rule. He died in 1242, the year after his younger brother Ogedei Khan, meaning that two Mongol khans were dead and that succession disputes would arise after their deaths.
